[0018] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0024] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0025] At present, electronic devices such as mobile phones usually have the function of automatically adjusting the screen brightness. For example, the electronic device in the related art sets a photosensitive element at a fixed position on the front of the screen module, detects the ambient light according to the photosensitive element to adjust the brightness of the screen according to the ambient light, thereby ensuring the comfort of the human eye when watching the screen. It is understandable that the front of the screen module refers to the side where the display surface of the screen module is located. However, in some usage scenarios, the photosensitive element is easily blocked. For example, when the user watches videos, plays games, etc., the electronic device will be used in landscape mode. At this time, the photosensitive element is easily blocked and affects the accuracy of ambient light detection, making it difficult to accurately adjust the screen brightness.

[0026] Alternatively, in the related art, there is also a solution of using dual photosensitive elements, that is, a photosensitive element is respectively arranged at a fixed position on the back and front of the electronic device, and the screen brightness is adjusted by combining the detection information of the two photosensitive elements on the ambient light. Although this solution can reduce the probability of the photosensitive element being completely blocked to a certain extent, the photosensitive element located on the back of the electronic device is easily affected by the shadow, so it cannot accurately reflect the ambient light intensity of the screen, and thus cannot accurately adjust the screen brightness.

[0027] In addition, in the related art, the light value of the ambient light can be obtained through the camera of the electronic device to adjust the screen brightness, but the camera may be blocked, so the screen brightness cannot be adjusted accurately. At the same time, the acquisition of the ambient light value through the camera requires the acquisition of an image, which leads to the risk of leaking user privacy.

[0028] In summary, the methods of adjusting screen brightness in related technologies will cause the photosensitive elements to be easily blocked in certain usage scenarios, resulting in inaccurate adjustment of the screen brightness and reducing the user experience.

[0029] In order to solve the above technical problems, the present disclosure provides an electronic device in which a moving mechanism can drive a photosensitive element to move, and a control unit is electrically connected to the screen module, the photosensitive element and the moving mechanism, so that the control unit can control the moving mechanism to drive the photosensitive element to move along a preset direction, and the preset direction has a component parallel to the display surface of the screen module, so as to avoid the photosensitive element being blocked and affecting the adjustment of the screen brightness. Such a design effectively avoids the problem that the photosensitive element is easily blocked in certain usage scenarios, ensures the accuracy of the detected ambient light, thereby effectively improving the accuracy of adjusting the screen brightness and enhancing the user experience.

[0030] An exemplary embodiment of the present disclosure provides an electronic device, which may be, for example, a mobile phone, a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc., and may also be a non-mobile device such as a personal computer (PC), a television (TV), a teller machine, or a self-service machine.

[0031] like Figure 1 As shown, the electronic device 1 includes a screen module 11, a photosensitive element 16, a moving mechanism and a control unit 101. The photosensitive element 16 is used to detect ambient light, and the photosensitive element 16 can be, for example, a light sensor. Exemplarily, the photosensitive element 16 can be set at the top of the display surface of the screen module 11; it can also be set at the bottom of the display surface of the screen module 11; it can also be set below the display surface of the screen module 11, in which case the position of the display surface of the screen module 11 corresponding to the photosensitive element 16 is set as a light-transmitting area for light to pass through; or it can also be set on the back of the electronic device 1, which is not specifically limited in this embodiment.

[0032] The moving mechanism is connected to the photosensitive element 16, and the moving mechanism can drive the photosensitive element 16 to move along a preset direction. For example, the moving mechanism can only drive the photosensitive element 16 to move along one preset direction, or can drive the photosensitive element 16 to move along multiple preset directions. The specific setting can be made according to actual needs and is not specifically limited here.

[0033] The preset direction has a component parallel to the display surface of the screen module 11. For example, the preset direction is parallel to the display surface of the screen module 11 to ensure that the distance between the photosensitive element 16 and the display surface can always be equal during the movement, thereby improving the efficiency of the photosensitive element 16 in avoiding obstructions and reducing ineffective movement of the photosensitive element 16; or the preset direction intersects with the display surface of the screen module 11 at an angle less than a right angle, as long as the photosensitive element 16 can avoid obstructions under the drive of the moving mechanism to avoid the photosensitive element 16 being blocked by the obstructions.

[0034] The control unit 101 is electrically connected to the screen module 11, the photosensitive element 16, and the moving mechanism, so that the control unit 101 can control the moving mechanism to drive the photosensitive element 16 to move and adjust the brightness of the screen module 11 according to the ambient light information detected by the photosensitive element 16, such as the ambient light intensity. For example, when the photosensitive element 16 is blocked, the control unit 101 controls the moving mechanism to drive the photosensitive element 16 to move, and when the photosensitive element 16 is not blocked, the control unit 101 adjusts the screen brightness of the screen module 11 according to the ambient light detected by the photosensitive element 16. Such a design effectively avoids the problem that the photosensitive element 16 is easily blocked in certain usage scenarios, ensures the accuracy of the detected ambient light, and effectively improves the accuracy of adjusting the screen brightness, avoids the screen module 11 from being displayed in high light in a dark light environment or in low light in a bright light environment, and improves the user's experience. In addition, by improving the accuracy of screen brightness adjustment, it can not only save energy consumption, but also reduce the user's visual fatigue, avoid irreversible effects on the user's vision, and thus help protect the user's vision.

[0035] Combination Figure 1 In one embodiment, the moving mechanism includes a bearing portion 12 and a driving device, and the photosensitive element 16 is disposed on the bearing portion 12. The driving device is drivingly connected to the bearing portion 12, and the bearing portion 12 is driven by the driving device to move along a preset direction. Such a setting form is not only convenient for setting the photosensitive element 16, but also makes the structure of the moving mechanism simple, and is convenient for processing and assembly. The driving device can be, for example, a linear motor, a linear cylinder, etc.

[0036] In one embodiment, the driving device includes a guide structure 15 and a driving assembly, the bearing part 12 is slidably connected to the guide structure 15, and the driving assembly is drivingly connected to the bearing part 12 to drive the bearing part 12 to move along the guide direction of the guide structure 15, and the guide direction of the guide structure 15 constitutes a preset direction, that is, the driving assembly drives the bearing part 12 to move along the preset direction. In this way, the movement of the bearing part 12 is limited by the guide structure 15, which can effectively improve the stability of the movement of the bearing part 12 and the accuracy of the movement trajectory, and avoid the bearing part 12 from deviating during movement to cause damage to other components inside the electronic device 1, thereby improving the reliability of the electronic device 1.

[0037] In one embodiment, the drive assembly includes a ball screw and a drive motor 14, such as Figure 1 and Figure 2As shown, the ball screw includes a screw rod 13, the axial direction of the screw rod 13 is parallel to the guide direction of the guide structure 15, and the drive motor 14 is connected to one end of the screw rod 13, so that when the drive motor 14 drives the screw rod 13 to rotate, the screw rod 13 can drive the bearing part 12 to move along the axial direction of the screw rod 13, thereby driving the bearing part 12 to move along the guide direction of the guide structure 15. The use of such a setting form can not only simplify the structure of the drive assembly, but also effectively improve the reliability and accuracy of the drive assembly compared to other transmission modes, thereby improving the reliability of the moving mechanism and the accuracy of the movement of the photosensitive element 16.

[0038] In one embodiment, the bearing part 12 is threadedly connected to the screw rod 13, and the guide structure 15 is connected to the bearing part 12 to limit the rotation of the bearing part 12 around the axis of the screw rod 13. When the drive motor 14 drives the screw rod 13 to rotate, under the action of the guide structure 15, the bearing part 12 can move along the axis of the screw rod 13, thereby driving the bearing part 12 to move along the guide direction of the guide structure 15. Such a design can effectively improve the stability of the movement of the bearing part 12 and the accuracy of the movement trajectory while making the drive component structure simple.

[0039] In another embodiment, the ball screw further includes a nut threadedly connected to the screw rod 13, the nut constitutes a bearing portion 12, and a photosensitive element 16 is disposed on the nut. Since the nut and the screw rod 13 are finished parts, and the movement of the photosensitive element 16 is achieved by making the nut constitute the bearing portion 12, the difficulty of processing and assembling the drive component can be reduced, and while reducing the processing cost, the assembly efficiency can also be effectively improved. Exemplarily, the nut is connected to the guide structure 15 to limit the rotation of the nut around the axis of the screw rod 13. In this way, the nut is prevented from deviating during movement to cause damage to other internal components of the electronic device 1, thereby improving the reliability of the electronic device 1 and the smoothness of the movement of the nut.

[0040] In another embodiment, the ball screw further includes a nut threadedly connected to the screw rod 13, the nut is fixedly connected to the bearing portion 12, and the screw rod 13 is passed through the bearing portion 12. When the drive motor 14 drives the screw rod 13 to rotate, the bearing portion 12 can move along the axial direction of the screw rod 13 under the action of the nut. Such a design can also reduce processing costs and improve the reliability and accuracy of the drive assembly. The bearing portion 12 in this embodiment is also connected to the guide structure 15 to limit the rotation of the bearing portion 12 around the axis of the screw rod 13, thereby improving the stability of the movement of the bearing portion 12 and the accuracy of the movement trajectory.

[0041] Combination Figure 1 and Figure 2In one embodiment, the guide structure 15 includes a guide rail, a guide groove 151 is provided on the guide rail, and a slider 121 is provided on the bearing portion 12, and the slider 121 is slidably connected to the guide groove 151. By connecting the slider 121 with the guide groove 151, when the bearing portion 12 moves, the slider 121 can slide along the guide groove 151 to limit and guide the bearing portion 12. With such a setting form, the structure of the guide structure 15 is simple and easy to process.

[0042] In one embodiment, the moving assembly further includes a limiting assembly, which is used to limit the movement range of the bearing portion 12 along a preset direction. In this way, the bearing portion 12 can be effectively prevented from derailing due to an excessive movement range, and the reliability of the moving mechanism can be further improved under the limiting action of the limiting assembly.

[0043] Combination Figure 1 In one embodiment, the limiting assembly includes a first limiting portion 18 and a second limiting portion 19 arranged at intervals along a preset direction. For example, the first limiting portion 18 and the second limiting portion 19 may be, for example, a protruding structure arranged in the guide groove 151, and the slider 121 is stopped by the protruding structure to limit the movement of the bearing portion 12; the first limiting portion 18 and the second limiting portion 19 may also be arranged at the top of the groove wall of the guide groove, and the bearing portion 12 is directly stopped to limit the movement of the bearing portion 12. The photosensitive element 16 is located between the first limiting portion 18 and the second limiting portion 19, and the moving mechanism drives the photosensitive element 16 to reciprocate between the first limiting portion 18 and the second limiting portion 19. With such a design, when the bearing portion 12 moves along the guiding direction of the guide structure 15, the derailment of the bearing portion 12 can be further avoided under the limiting action of the first limiting portion 18 and the second limiting portion 19, thereby effectively improving the reliability of the moving mechanism.

[0044] For example, in the process of controlling the movement of the carrying portion 12, the number of times the first limit portion 18 and the second limit portion 19 are triggered can be reduced by reserving a safety distance, thereby extending the service life of the first limit portion 18 and the second limit portion 19. For example, the control unit 101 controls the drive motor 14 to rotate in a first direction (for example, counterclockwise) to drive the carrying portion 12 to move in a second direction (for example, Figure 1 The first limiter 18 sends a signal to the control unit 101. Then, the control unit 101 controls the drive motor 14 to rotate two circles along the third direction (for example, clockwise). At this time, the current position of the marking carrier 12 is the initial position X0. The control unit 101 controls the drive motor 14 to continue to rotate along the third direction to drive the carrier 12 to the fourth direction (for example, clockwise). Figure 1The second limiter 19 sends a signal to the control unit 101. Then, the control unit 101 controls the driving motor 14 to rotate two circles in the first direction. At this time, the current position of the marking bearing unit 12 is the maximum stroke X1. In this way, the safe distance during the movement of the bearing unit 12 is reserved.

[0045] In another embodiment, there are multiple preset directions, the moving mechanism includes a bearing portion 12 and multiple conveying tracks, and the photosensitive element 16 is disposed on the bearing portion 12. The multiple conveying tracks correspond one-to-one to the multiple preset directions, and the conveying tracks are used to convey the bearing portion 12 along the corresponding preset directions. Exemplarily, the multiple preset directions are sequentially connected to form a rectangle, and correspondingly, the multiple conveying tracks correspond one-to-one to the multiple preset directions and are also sequentially connected to form a rectangular structure. With such a setting, the moving range of the bearing portion 12 can be effectively expanded, thereby improving the flexibility of driving the photosensitive element 16 to move away from obstructions, which is beneficial to improving the efficiency of adjusting the screen brightness, and further enhancing the user experience.

[0046] In one embodiment, a plurality of conveying tracks are arranged crosswise, and a transfer mechanism is arranged at the crosswise position, and the transfer mechanism may be, for example, a roller. The transfer mechanism can transfer the carrying part 12 between different conveying tracks. Such a design improves the smoothness of the transition of the carrying part 12 between different conveying tracks, thereby effectively improving the stability and speed of the carrying part 12 when moving, and further improving the efficiency of adjusting the screen brightness and the reliability of the electronic device 1.

[0047] Among them, the user can manually control the movement of the photosensitive element 16 to move the photosensitive element 16 to a position that is not easily blocked, or the control unit 101 can automatically control the movement of the photosensitive element 16. For example, in one embodiment, the electronic device 1 also includes a distance detection element 17, and the distance detection element 17 can be, for example, a distance sensor. The distance detection element 17 is connected to the moving mechanism so that the moving mechanism drives the distance detection element 17 and the photosensitive element 16 to move synchronously. Exemplarily, the distance detection element 17 and the photosensitive element 16 are both arranged on the bearing portion 12 of the moving mechanism, so as to achieve the synchronous movement of the distance detection element 17 and the photosensitive element 16. The distance detection element 17 detects the distance between the photosensitive element 16 and the obstruction. Exemplarily, the distance detection element 17 and the photosensitive element 16 are both located on the same surface of the bearing portion 12, and the distance between the distance detection element 17 and the display surface of the display module is equal to the distance between the photosensitive element 16 and the display surface of the display module. In this way, the accuracy of the distance detection element 17 in detecting the distance between the photosensitive element 16 and the obstruction can be effectively improved.

[0048] The distance detection element 17 is electrically connected to the control unit 101, and the control unit 101 can control the movement of the moving mechanism according to the distance detected by the distance detection element 17, so as to drive the photosensitive element 16 to move and prevent the photosensitive element 16 from being blocked. For example, when the distance detection element 17 detects that the distance between the photosensitive element 16 and the blocking object is relatively close, it means that the photosensitive element 16 is blocked by the blocking object. At this time, the control unit 101 controls the moving mechanism to drive the distance detection element 17 and the photosensitive element 16 to move synchronously. In this process, the distance detection element 17 detects the distance between the photosensitive element 16 and the blocking object in real time until the distance detection element 17 detects that the distance between the photosensitive element 16 and the blocking object is relatively far, which means that the photosensitive element 16 is not blocked by the blocking object. At this time, the control unit 101 controls the moving mechanism to stop driving. It can be understood that the above control process can be implemented by a pure circuit, for example, the signal detected by the distance detection element 17 and the size of the preset distance signal can be compared by a comparator to control whether the moving mechanism drives the photosensitive element 16 to move.

[0049] By setting the distance detection element 17, it is convenient to judge whether the photosensitive element 16 is blocked by an obstruction, thereby improving the timeliness and effectiveness of the control unit 101 controlling the moving mechanism, improving the accuracy of the movement of the photosensitive element 16, and further improving the accuracy of adjusting the screen brightness.

[0050] For example, when the electronic device 1 in this embodiment is used, the specific process is as follows:

[0051] When the electronic device 1 is turned on, the control unit 101 controls the driving motor 14 to rotate in a first direction (for example, counterclockwise) to drive the carrying unit 12 to rotate in a second direction (for example, Figure 1 The marking bearing portion 12 moves in the right direction (in the right direction shown in FIG. 1 ) until the bearing portion 12 contacts the first limit portion 18. The first limit portion 18 sends a signal to the control portion 101. Then the control portion 101 controls the driving motor 14 to rotate two circles along the third direction (for example, clockwise). At this time, the current position of the marking bearing portion 12 is the initial position X0.

[0052] The control unit 101 controls the driving motor 14 to continue to rotate along the third direction to drive the carrying unit 12 to the fourth direction (eg Figure 1 The marking bearing portion 12 moves in the left direction (in the left direction shown in FIG. 1 ) until the bearing portion 12 contacts the second limit portion 19. The second limit portion 19 sends a signal to the control portion 101. Then the control portion 101 controls the driving motor 14 to rotate two circles in the first direction. At this time, the current position of the marking bearing portion 12 is the maximum stroke X1.

[0053] The above is a process of detecting the travel of the carrying part 12 of the mobile mechanism after the electronic device 1 is turned on. With such a design, a safe distance can be reserved for the moving range of the carrying part 12, reducing the number of times the first limit part 18 and the second limit part 19 are triggered, thereby extending the service life of the first limit part 18 and the second limit part 19.

[0054] After that, the photosensitive element 16 and the distance detection element 17 begin to be loaded to adjust the screen brightness.

[0055] The specific process of adjusting the screen brightness of the screen module 11 is as follows:

[0056] Register the photosensitive element 16 and the distance detection element 17, and monitor the data of the photosensitive element 16 and the distance detection element 17. In this step, the timing of registering the photosensitive element 16 and the distance detection element 17 includes when the electronic device 1 turns on the screen after turning on the screen, when the screen is turned on again after turning off the screen, and when the electronic device 1 turns on the automatic screen brightness adjustment function.

[0057] When it is determined based on the detection of the distance detection element 17 that the photosensitive element 16 is not blocked by an obstruction, the light sensitivity value detected by the photosensitive element 16 is reported. If the light sensitivity value is the first light sensitivity data, the control unit 101 adjusts the screen brightness according to the current light sensitivity value, and sets the light sensitivity threshold T1 for the next screen dimming and the light sensitivity threshold Th for brightening. Exemplarily, when setting the light sensitivity threshold T1 for the next screen dimming, it can be set according to the current light sensitivity value and the preset coefficient. For example, the product of the current light sensitivity value and the preset coefficient is used as the light sensitivity threshold T1 for the next screen dimming. The preset coefficient can be set according to specific needs, for example, it can be 0.8 or 0.5. When setting the light sensitivity threshold Th for the next screen brightening, for example, the sum of the current light sensitivity value and the light sensitivity adjustment value can be used as the light sensitivity threshold Th for the next screen brightening. The light sensitivity adjustment value can be set according to specific needs, for example, it can be 10Lux, 20Lux or 30Lux. If the light sense value is not the first light sense data, it is necessary to determine whether the light sense value is less than the light sense threshold T1 for dimming or greater than the light sense threshold Th for brightening. If the conditions are met, the control unit 101 adjusts the screen brightness according to the current light sense value and resets the light sense threshold T1 for dimming the screen and the light sense threshold Th for brightening the screen next time. If the conditions are not met, the data of the photosensitive element 16 and the distance detection element 17 are continuously monitored.

[0058] When it is determined according to the detection of the distance detection element 17 that the photosensitive element 16 is blocked by an obstruction, it is necessary to control the moving mechanism to drive the movement of the photosensitive element 16 to obtain ambient light. The specific process is as follows:

[0059] The control unit 101 obtains the position X of the carrying unit 12, and then compares the absolute value of (X-X0) with the absolute value of (X1-X) to determine whether the current position of the carrying unit 12 is closer to the initial position X0 or the maximum stroke X1.

[0060] If the current position of the carrying part 12 is closer to the initial position X0, the control unit 101 controls the drive motor 14 to drive the carrying part 12 to move toward the initial position X0 until it moves to the initial position X0, and then the control unit 101 controls the drive motor 14 to drive the carrying part 12 to move toward the maximum stroke X1 until it moves to the maximum stroke X1, and then the control unit 101 controls the drive motor 14 to drive the carrying part 12 to move toward the initial position X0 again. By analogy, the control unit 101 controls the carrying part 12 to move back and forth between the initial position X0 and the maximum stroke X1. In this process, if the detection of the distance detection element 17 determines that the photosensitive element 16 is not blocked by an obstruction, the control unit 101 controls the drive motor 14 to stop driving, and obtains the light sensitivity value detected by the photosensitive element 16 to adjust the screen brightness.

[0061] If the current position of the carrying part 12 is closer to the maximum stroke X1, the control part 101 controls the drive motor 14 to drive the carrying part 12 to move toward the maximum stroke X1 until it moves to the maximum stroke X1, and then the control part 101 controls the drive motor 14 to drive the carrying part 12 to move toward the initial position X0 until it moves to the initial position X0, and then the control part 101 controls the drive motor 14 to drive the carrying part 12 to move toward the maximum stroke X1 again. By analogy, the control part 101 controls the carrying part 12 to move back and forth between the initial position X0 and the maximum stroke X1. In this process, if the detection of the distance detection element 17 determines that the photosensitive element 16 is not blocked by an obstruction, the control part 101 controls the drive motor 14 to stop driving, and obtains the light sensitivity value detected by the photosensitive element 16 to adjust the screen brightness.

[0062] In one embodiment, the screen module 11 includes a display panel and a cover plate. The cover plate is arranged on the display surface of the display panel. The cover plate can be a cover plate made of transparent materials such as glass. The display panel is used to display the picture, and the cover plate is arranged on the display surface of the display panel to protect the display panel and prevent the display panel from being damaged by puncture, wear and tear, thereby ensuring the display effect of the electronic device 1.

[0063] The photosensitive element 16 is located on the back of the cover plate of the screen module 11. It is understandable that the back of the cover plate refers to the side surface of the cover plate facing the display panel. The photosensitive surface of the photosensitive element 16 faces the cover plate, which ensures that the photosensitive element 16 can detect the ambient light normally, thereby improving the accuracy of adjusting the screen brightness. The projections of the photosensitive element 16 and the display panel of the screen module 11 in a plane parallel to the display surface of the screen module 11 are arranged separately from each other. Exemplarily, the photosensitive element 16 can be arranged at the top or bottom of the display surface of the screen module 11. Such a design can effectively avoid interference between the photosensitive element 16 and the display surface of the screen module 11, thereby ensuring normal display of the display surface.

[0064] In another embodiment, the photosensitive element 16 is located on the back of the display panel of the screen module 11. It is understandable that the back of the display panel refers to the side surface opposite to the display surface of the display panel. In order to ensure the normal detection of ambient light by the photosensitive element 16, the area on the display panel corresponding to the moving range of the photosensitive element 16 is set as a light-transmitting area, and the photosensitive surface of the photosensitive element 16 faces the display panel. Such a setting can also improve the accuracy of the photosensitive element 16 in detecting ambient light, thereby improving the accuracy of adjusting the screen brightness and enhancing the user experience.

[0065] In addition, the photosensitive element 16 can also be arranged on the back of the electronic device 1, that is, the photosensitive element 16 is arranged on the side surface where the back shell of the electronic device 1 is located. In this way, interference between the photosensitive element 16 and the display surface of the screen module 11 can be effectively avoided, thereby ensuring the normal display of the display surface while ensuring the normal detection of ambient light by the photosensitive element 16, thereby improving the accuracy of adjusting the screen brightness.
